[Abstract] Objective: To analyze the correlation with T stage, histologic differentiation grade of esophageal cancer.Materials and Methods: A total of 45 pathologically confirmed patients with esophageal cancer were included. Mean tumor apparent diffusion coefficient (ADC) for different histologic differentiation grades, T-stages were measured and compared.Results: The average ADC value of esophageal cancer was negatively correlated with the T staging, and the ADC value decreased with the increase of T staging. The results of Spearson correlation analysis showed that average ADC value was negatively correlated with T stage (r=-0.645, P<0.01). The average ADC value of the low-differentiation group was lower than that of the medium-high differentiation group (1.8514±0.40295)×10-3 mm2/s, 1.7125±0.37767)×10-3 mm2/s). There were no significant differences in ADC value no matter what kind of histological grade.Conclusions: DWI was useful for evaluating T stage of esophageal cancer, and can reflect the clinical T stage of esophageal cancer, providing help for clinical treatment.
